Description

Technical Field

[0001] The present application belongs to the technical field of combustion devices, and in particular relates to a gas burner head and a gas stove. Background Art

[0002] A combustion device is a kitchen appliance that uses a direct flame to heat a gaseous fuel, such as liquefied petroleum gas (liquid), manufactured gas, or natural gas. Direct flame is generated by introducing the gas fuel into the gas stove, mixing it with air, and igniting the mixture.

[0003] In related technologies, in order to make the gas fuel and air mix more fully, the gas pipeline can be extended. However, this method will cause the bends in the gas pipeline to block the mixed gas, resulting in a blocked gas path in the gas pipeline. Summary of the Invention

[0004] The present application aims to at least to some extent solve the technical problem of gas pipes in existing gas stoves being blocked due to bending. To this end, the present application provides a gas burner head and a gas stove.

[0005] A gas burner provided in an embodiment of the present application includes a burner body, wherein the burner body has a gas mixing chamber, a first ejection chamber, a guide chamber, and an air supply chamber. The burner body is provided with a gas inlet and a first air inlet connected to the gas mixing chamber. The gas mixing chamber and the guide chamber are respectively arranged on both sides of the air supply chamber, and the guide chamber is connected to the air supply chamber. Both ends of the first ejection chamber are respectively connected to the gas mixing chamber and the guide chamber.

[0006] The first ejection cavity and the flow guide cavity are connected in a curved transition manner, and the flow guide cavity and the air supply cavity are also connected in a curved transition manner.

[0007] In the gas burner disclosed in the embodiment of the present application, the gas mixing chamber and the guide chamber are arranged on both sides of the gas supply chamber, so that there is a certain distance between the gas mixing chamber and the guide chamber, and the first ejection chamber is connected between the gas mixing chamber and the gas supply chamber, so that the mixed gas in the gas mixing chamber needs to pass through the first ejection chamber and the guide chamber before it can enter the gas supply chamber, thereby increasing the distance the gas reaches the gas supply chamber, so that the mixed gas is fully mixed during the movement.

[0008] The curved transition connection between the first ejection chamber and the guide chamber, the curved transition connection between the guide chamber and the air supply chamber, after the gas reaches the connection between the first ejection chamber and the guide chamber, and the connection between the guide chamber and the air supply chamber, the transition connection can guide the mixed gas into the first ejection chamber and the guide chamber to prevent the mixed gas from being retained and accumulated at the above-mentioned connection, thereby making the gas path between the mixing chamber and the air supply chamber unobstructed.

[0009] In some embodiments, the first ejection cavity has a first end connected to the flow guide cavity and a second end connected to the gas mixing cavity, and one end of the flow guide cavity connected to the gas supply cavity is bent toward the second end.

[0010] In this way, the air supply chamber connected to the guide chamber can be relatively close to the air mixing chamber, so that the length of the overall structure formed by the first ejection chamber, the guide chamber and the air supply chamber is relatively short, and the length of the burner body does not need to be set too long, which ultimately makes the gas burner easy to install and place.

[0011] In some embodiments, the air supply cavity is disposed in contact with an outer wall of the first ejection cavity.

[0012] In this way, there is no gap between the air supply cavity and the first ejection cavity, thereby making the internal structure of the burner body more compact.

[0013] In some embodiments, a second ejection cavity is further provided in the burner body, and the air supply cavity includes a first cavity portion and a second cavity portion, the first cavity portion is arranged around the second cavity portion, the first cavity portion is connected to the guide cavity, one end of the second ejection cavity is connected to the gas mixing cavity, and the other end of the second ejection cavity is connected to the second cavity portion.

[0014] Gas can be supplied to the second cavity portion separately through the second ejection cavity, thereby preventing the mixed gas in the first ejection cavity from interfering with the mixed gas in the second ejection cavity.

[0015] In some embodiments, an extension direction of the second ejection cavity is offset from a center of the second cavity portion.

[0016] In this way, the length of the second ejection cavity can be increased, so that the mixed gas is mixed more fully in the first ejection cavity.

[0017] In some embodiments, an extension direction of the second ejection cavity is tangent to an edge of the second cavity portion, and the second ejection cavity and the second cavity portion are also connected in a curved transition.

[0018] The second ejection cavity is tangent to the edge of the second cavity portion, so that the length of the second ejection cavity can be maximized.

[0019] In some embodiments, the second ejection cavity has a third end connected to the second cavity portion and a fourth end connected to the gas mixing cavity, and the third end is bent toward the fourth end.

[0020] This allows the second cavity connected to the third end to be relatively close to the mixing cavity, thereby making the overall structural length connecting the second injection cavity and the enemy cavity shorter, thereby reducing the length of the burner body, and ultimately making the gas burner easy to install and place.

[0021] In some embodiments, a partition is provided in the gas mixing chamber to separate the gas mixing chamber into a first gas mixing portion and a second gas mixing portion, the first ejection chamber is communicated with the first gas mixing portion, and the second ejection chamber is communicated with the second gas mixing portion.

[0022] The first gas mixing portion and the second gas mixing portion are independent of each other, which can prevent the gas flowing into the first injection cavity and the gas flowing into the second injection cavity from interfering with each other.

[0023] In some embodiments, the burner body is further provided with a second air inlet connected to the air mixing chamber, and the second air inlet is provided with a detachable sealing plate so that the second air inlet can be opened and closed.

[0024] The second air inlet that can be opened and closed enables the gas burner to be in an upper air inlet mode, or a upper and lower air inlet mode at the same time.

[0025] The present application also proposes a gas stove comprising the above-mentioned gas burner.

[0026] In some embodiments, the gas stove further includes a gas distribution plate, which is arranged on the burner body and opposite to the gas supply cavity. A first connecting member is provided on the burner body, and the gas distribution plate has a second connecting member. The first connecting member cooperates with the second connecting member to limit the radial displacement of the gas distribution plate.

[0027] The cooperation between the first connecting piece and the second connecting piece enables the gas distribution plate to remain stable. BRIEF DESCRIPTION OF THE DRAWINGS

[0048] The present application is described below with reference to specific embodiments and with reference to the accompanying drawings:

[0049] Example 1

[0050] Please refer to Figures 1 to 11 The present invention discloses a gas burner head that can be used in a gas stove. A gas stove is a device that burns gas fuel, mixing the gas fuel with air to form a mixed gas, igniting the mixed gas through an ignition device to produce a flame, and maintaining the burning flame for a long time by continuously supplying the mixed gas.

[0051] The gas burner in this embodiment includes a burner body 100. The burner body 100 is the basic component of the gas burner and provides a mounting base for at least some of the other components of the gas burner. Because a gas stove generates high-temperature flames during operation, the burner body 100 can be made of a high-temperature-resistant metal material, specifically a copper alloy. This prevents deformation of the burner body 100 during operation. Of course, it can also be made of a high-temperature-resistant ceramic material. This application does not impose any restrictions on the specific material of the burner body 100.

[0052] The burner body 100 comprises a gas mixing chamber 110, a flow guide chamber 130, a gas supply chamber 140, and a first ejection chamber 120. These multiple chambers are all disposed within the burner body 100. Specifically, the burner body 100 can be constructed as an integrated structure, formed by casting within the burner body 100. This provides the burner body 100 with superior structural strength, thereby enhancing its reliability and durability. This also reduces the difficulty of manufacturing the burner body 100, facilitating large-scale production.

[0053] The burner body 100 is provided with a gas inlet 111 and a first air inlet 112. The gas inlet 111 can be connected to a gas pipeline, allowing gas fuel to enter the burner body 100 through the gas inlet 111. The first air inlet 112 is an opening provided on the surface of the burner body 100, allowing external air to enter the burner body 100 through the first air inlet 112. Both the gas inlet 111 and the first air inlet 112 are connected to the gas mixing chamber 110, so that both gas fuel and air can enter the gas mixing chamber 110 and begin to mix.

[0054] After mixing, the gas fuel and air can enter the gas supply chamber 140. An ignition device can be installed inside the gas supply chamber 140 or outside the gas supply chamber 140 near the gas supply chamber 140. The ignition device can ignite the mixed gas in the gas supply chamber 140 to produce a flame. The guide chamber 130 and the gas mixing chamber 110 are arranged on both sides of the gas supply chamber 140, and the guide chamber 130 and the gas mixing chamber 110 are connected through the first ejection chamber 120. The guide chamber 130 and the gas mixing chamber 110 are separated by the gas supply chamber 140, so that there is a certain distance between the guide chamber 130 and the gas mixing chamber 110. Therefore, the mixed gas in the gas mixing chamber 110 needs to pass through the first ejection chamber 120 and the guide chamber 130 on the way to the gas supply chamber 140. This can increase the distance the mixed gas travels to reach the gas supply chamber 140, so that the mixed gas can be fully mixed during the process of passing through the first ejection chamber 120 and the guide chamber 130.

[0055] When the gas fuel and air are fully mixed and enter the gas supply chamber 140, the ignition device ignites the fully mixed gas mixture, causing the mixed gas to burn more completely, thereby making the flame produced after the mixed gas ignites stronger. At the same time, because the mixed gas in the gas mixing chamber 110 must pass through the first ejection chamber 120 and the guide chamber 130 to enter the gas supply chamber 140, this ensures that the mixed gas entering the gas supply chamber 140 is fully mixed, thereby maintaining the flame intensity of the mixed gas in the gas supply chamber 140 after ignition.

[0056] The above-mentioned guide chamber 130 can be set to be bent relative to the first injection chamber 120, so that after the mixed gas reaches the end of the first injection chamber 120, the inner wall of the end of the first injection chamber 120 has the function of blocking the mixed gas, so that the flow rate of the mixed gas is slowed down. At the same time, the mixed gas needs to turn and enter the guide chamber 130. In this way, the time required for the mixed gas to pass through the first injection chamber 120 is longer, and the mixed gas can be mixed more fully.

[0057] The above-mentioned air supply chamber 140 can be set to bend relative to the guide chamber 130, so that after the mixed gas enters the guide chamber 130 and moves to the connection between the guide chamber 130 and the air supply chamber 140, it will be blocked by the inner wall of the guide chamber 130, thereby slowing down the flow rate of the mixed gas. At the same time, the mixed gas needs to turn and enter the air supply chamber 140, which can make the mixed gas pass through the guide chamber 130 for a longer time, so that the mixed gas is further fully mixed.

[0058] The mixed gas needs to make multiple turns while passing through the first ejection chamber 120 and the guide chamber 130, so that the mixed gas can be fully mixed. Of course, multiple first ejection chambers 120 and guide chambers 130 can be provided, and the two adjacent chambers are bent relative to each other. This can further increase the stroke of the mixed gas and make the gas fuel and air mix more fully. At the same time, the first ejection chamber 120, the guide chamber 130, and the air supply chamber 140 that are bent relative to each other can also increase the length of the gas path between the mixing chamber 110 and the air supply chamber 140 while keeping the distance between the mixing chamber 110 and the air supply chamber 140 unchanged. Accordingly, the volume of the burner body 100 does not need to be set too large, so that the space occupied by the burner body 100 is also small.

[0059] Since the above-mentioned first induction chamber 120 and the guide chamber 130 are bent to each other, and the guide chamber 130 and the air supply chamber 140 are bent to each other, when the mixed gas passes through the connection between the first induction chamber 120 and the guide chamber 130, and the connection between the guide chamber 130 and the air supply chamber 140, the inner wall of the first induction chamber 120 and the inner wall of the guide chamber 130 will block the airflow formed by the mixed gas. Although this can extend the time that the mixed gas stays in the first induction chamber 120 and the guide chamber 130, it may also cause the mixed gas to be retained and accumulated at the above-mentioned connection, thereby causing the air path between the mixing chamber 110 and the air supply chamber 140 to be blocked.

[0060] Therefore, the first ejection chamber 120 and the guide chamber 130 can be connected by a curved transition, which can guide the mixed gas. Specifically, the guide chamber 130 is arranged to bend relative to the first ejection chamber 120. When the mixed gas reaches the connection between the guide chamber 130 and the first ejection chamber 120, the curved transition can guide the mixed gas through the aforementioned connection, allowing the mixed gas to enter the guide chamber 130 smoothly. This prevents the mixed gas from being blocked by the inner wall of the first ejection chamber 120 and being retained and accumulated in the first ejection chamber 120, thereby ensuring an unobstructed gas path between the first ejection chamber 120 and the guide chamber 130.

[0061] Specifically, the inner wall of the first induction chamber 120 adjacent to the guide chamber 130 is bent toward the guide chamber 130, so that when the mixed gas reaches the part of the first induction chamber 120 adjacent to the guide chamber 130, the mixed gas can move along the curved inner wall of the first induction chamber 120 under the influence of the wall attachment effect. The curved inner wall can guide the mixed gas, thereby preventing the airflow formed by the mixed gas from directly impacting the inner wall of the first induction chamber 120 and being blocked, so that the mixed gas can smoothly pass through the connection between the first induction chamber 120 and the guide chamber 130.

[0062] At the same time, the guide chamber 130 and the air supply chamber 140 can also be connected by a curved transition. Specifically, the air supply chamber 140 is bent relative to the guide chamber 130. When the mixed gas reaches the connection between the guide chamber 130 and the air supply chamber 140, the curved transition can guide the mixed gas through the above-mentioned connection, so that the mixed gas can smoothly enter the air supply chamber 140, preventing the mixed gas from being blocked by the inner wall of the guide chamber 130 and being retained and accumulated in the guide chamber 130, thereby making the air path between the guide chamber 130 and the air supply chamber 140 normal.

[0063] Specifically, the inner wall of the guide chamber 130 adjacent to the second opening is curved toward the air supply chamber 140, so that when the mixed gas reaches the part of the guide chamber 130 adjacent to the air supply chamber 140, the mixed gas can move along the curved inner wall of the guide chamber 130 under the influence of the wall attachment effect, thereby preventing the airflow formed by the mixed gas from directly impacting the inner wall of the guide chamber 130 and being blocked, thereby allowing the mixed gas to smoothly pass through the connection between the guide chamber 130 and the air supply chamber 140.

[0064] By setting a curved transition at the connection between the first injection chamber 120 and the guide chamber 130, and setting a curved transition at the connection between the guide chamber 130 and the air supply chamber 140, the air path between the mixing chamber 110 and the air supply chamber 140 is unobstructed, so that the mixed gas can continuously and stably reach the air supply chamber 140, and finally the flame generated by the ignition device igniting the mixed gas in the air supply chamber 140 is stable.

[0065] In the gas burner disclosed in the embodiment of the present application, the mixing chamber 110 and the guide chamber 130 are arranged on both sides of the air supply chamber 140, so that there is a certain distance between the mixing chamber 110 and the guide chamber 130, and the first ejection chamber 120 is connected between the mixing chamber 110 and the air supply chamber 140, so that the mixed gas in the mixing chamber 110 needs to pass through the first ejection chamber 120 and the guide chamber 130 before it can enter the air supply chamber 140, thereby increasing the distance the gas travels to reach the air supply chamber 140, so that the mixed gas is fully mixed during the movement.

[0066] The curved transition connection between the first injection chamber 120 and the mixing chamber 110, and the curved transition connection between the mixing chamber 110 and the air supply chamber 140. After the gas reaches the connection between the first injection chamber 120 and the mixing chamber 110, and the connection between the mixing chamber 110 and the air supply chamber 140, the transition connection can guide the mixed gas into the first injection chamber 120 and the mixing chamber 110 to prevent the mixed gas from being retained and accumulated at the above-mentioned connection, thereby making the gas path between the mixing chamber 110 and the air supply chamber 140 unobstructed.

[0067] In some embodiments, the first ejection chamber 120 and the flow guide chamber 130 may be connected by a bend transition. Specifically, the inner wall of the first ejection chamber 120 near the flow guide chamber 130 may be configured as an inclined surface inclined toward the flow guide chamber 130. This inclined surface may also guide the mixed gas, allowing the mixed gas to move along the inclined surface into the flow guide chamber 130. Correspondingly, the flow guide chamber 130 and the air supply chamber 140 may also be connected by a bend transition, which may also guide the mixed gas at the connection between the ejection chamber 130 and the air supply chamber 140 into the air supply chamber 140.

[0068] Of course, the above-mentioned inclined surface can also be set as a multi-segment inclined surface, a multi-segment curved surface or a mixture of a multi-segment inclined surface and a multi-segment curved surface, which can guide the mixed gas and ensure smooth gas flow between the gas mixing chamber 110 and the gas supply chamber 140.

[0069] In some embodiments, the first inlet chamber 120 has a first end and a second end, wherein the first end is connected to the guide chamber 130, and the second end is connected to the mixing chamber 110, and the end of the guide chamber 130 connected to the air supply chamber 140 is bent toward the second end of the first inlet chamber 120, so that the air supply chamber 140 connected to the guide chamber 130 is relatively close to the mixing chamber 110, so that the length of the overall structure formed by the first inlet chamber 120, the guide chamber 130 and the air supply chamber 140 is relatively short, and the length of the burner body 100 does not need to be set too long, and finally the gas burner can be easy to install and place.

[0070] Specifically, the portion of the first ejection cavity 120 adjacent to the flow guide cavity 130 is the first portion 121, and the portion of the first ejection cavity 120 away from the flow guide cavity 130 is the second portion 122. The flow guide cavity 130 is disposed opposite the first portion 121 of the first ejection cavity 120. Thus, the flow guide cavity 130 is not disposed along the extension direction of the first ejection cavity 120. Accordingly, the overall structure of the flow guide cavity 130 and the first ejection cavity 120 after connection is more compact. The air supply cavity 140 is disposed opposite the second portion 122 of the first ejection cavity 120. Thus, both the air supply cavity 130 and the air supply cavity 140 are disposed on one side of the first ejection cavity 120. This makes the structures of the first ejection cavity 120, the flow guide cavity 130, and the air supply cavity 140 more compact, occupying less space within the burner body 100, and accordingly, reducing the volume of the burner body 100.

[0071] The above-mentioned air supply cavity 140 can also be set to be in contact with the outer wall of the first ejection cavity 120. Specifically, the outer wall of the first ejection cavity 120 is the inner wall of the air supply cavity 140, and the outer wall of the air supply cavity 140 is the inner wall of the first ejection cavity 120. In this way, there is no gap between the first ejection cavity 120 and the air supply cavity 140, thereby further making the internal structure of the furnace head body 100 more compact.

[0072] In some embodiments, the gas supply cavity 140 is composed of a first cavity 141 and a second cavity 142. Specifically, the first cavity 141 is arranged around the second cavity 142, and a mixture of gas fuel and air can enter the first cavity 141 and the second cavity 142. The ignition device can ignite the mixed gas in the first cavity 141 and the mixed gas in the second cavity 142, thereby generating a central flame above the first cavity 141 and a peripheral flame surrounding the central flame above the first cavity 141. The central flame and the peripheral flame act on the object to be heated simultaneously, so that the object to be heated is heated evenly, thereby improving the heating effect of the gas stove using the gas burner head.

[0073] Of course, the first cavity 141 and the second cavity 142 may be arranged relative to each other or cross-arranged. The present application does not limit the specific arrangement of the first cavity 141 and the second cavity 142 .

[0074] The first cavity 141 is in communication with the diversion cavity 130. The mixed gas in the gas mixing cavity 110 passes through the first ejection cavity 120 and the diversion cavity 130 before entering the first cavity 141. A second ejection cavity 150 is also provided within the burner body 100. One end of the second ejection cavity 150 is in communication with the gas mixing cavity 110, and the other end of the second ejection cavity 150 is in communication with the second cavity 142. This allows some of the mixed gas in the gas mixing cavity 110 to pass through the second ejection cavity 150 and enter the second cavity 142, thereby filling the second cavity 142 with the mixed gas. The mixed gas is injected into the first cavity 141 and the second cavity 142 separately through the first injection cavity 120 and the second injection cavity 150. Since the first injection cavity 120 and the second injection cavity 150 are independent of each other, the airflow through the first injection cavity 120 and the airflow through the second injection cavity 150 are also independent of each other and do not interfere with each other, so that the amount of the mixed gas in the first cavity 141 and the second cavity 142 can be kept stable, and finally the flame formed above the first cavity 141 and the flame formed above the second cavity 142 can be kept stable.

[0075] In some embodiments, the second ejection chamber 150 can be set so that its extension direction is offset from the center of the second cavity portion 142. Specifically, the axis of the second ejection chamber 150 will not intersect with the central part of the second cavity portion 142. In this way, the flow direction of the mixed gas discharged from the second ejection chamber 150 will not be directly toward the center of the second cavity portion 142. In this way, after the mixed gas enters the second cavity portion 142, it will take a certain amount of time to diffuse and fill the second cavity portion 142. The mixed gas can be further mixed when it reaches the second cavity portion 142, so that the gas fuel and air can contact more fully, and ultimately the mixed gas in the second cavity portion 142 can burn more fully.

[0076] The second chamber 142 can be configured as a circular cross-section along its height, so that the second chamber 142 has an overall cylindrical structure. Accordingly, the inner wall of the second chamber 142 is an arc-shaped inner wall. This inner wall serves to guide the mixed gas. Under the influence of the Coanda effect, the mixed gas entering the second chamber 142 through the second ejection chamber 150 can flow along the arc-shaped inner wall of the second chamber 142, thereby ensuring a uniform concentration of the mixed gas in various parts of the second chamber 142. Furthermore, the second ejection chamber 150 can be configured to extend tangentially to the second chamber 142. This allows the second ejection chamber 150 to be located at the outermost edge of the second chamber 142, so that the mixed gas entering the second chamber 142 through the second ejection chamber 150 is at its greatest distance from the center of the second chamber 142.

[0077] Of course, the cross-section of the above-mentioned second cavity portion 142 in its height direction can also be set to a rectangle, and one end of the second injection cavity 150 can be set to be connected to the corner of the second cavity portion 142, so that the distance between the connection between the second injection cavity 150 and the second cavity portion 142 and the center of the second cavity portion 142 can be maximized, so that the above-mentioned effect of the second injection cavity 150 being tangent to the edge of the second cavity portion 142 can be achieved.

[0078] Of course, to ensure more complete mixing of the mixed gas during its passage through the second ejection chamber 150, the second ejection chamber 150 may be curved, specifically, by a spiral bend or a zigzag bend. This increases the length of the second ejection chamber 150, thereby extending the distance the mixed gas travels to reach the second chamber portion 142. This application does not impose any limitation on the specific shape of the second ejection chamber 150.

[0079] In some embodiments, the second ejection cavity 150 has a third end and a fourth end, wherein the third end is in communication with the second cavity portion 142, and the fourth end is in communication with the gas mixing cavity 110. The third end is bent toward the fourth end, so that the second cavity portion 142 connected to the third end is relatively close to the gas mixing cavity 110, thereby shortening the overall length of the structure connecting the second ejection cavity 150 and the second cavity portion 142, thereby reducing the length of the burner body 100, and ultimately making the gas burner easier to install and place.

[0080] Specifically, the second cavity portion 142 is located on one side of the extension direction of the second induction cavity 150, and the projection of the second cavity portion 142 on the second induction cavity 150 is located within the second induction cavity 150. This makes the overall structure formed by the connection between the second cavity portion 142 and the second induction cavity 150 more compact, thereby facilitating the arrangement of the second induction cavity 150 and the second cavity portion 142 in the furnace head body 100.

[0081] In some embodiments, a partition 300 may be provided within the mixing chamber 110. The partition 300 can separate the mixing chamber 110 into multiple regions. Specifically, the partition 300 defines a first mixing section 114 and a second mixing section 115 on either side. Thus, the gas fuel entering the mixing chamber 110 through the gas inlet 111 is divided into two portions by the partition 300, with the two portions of gas fuel located in the first mixing section 114 and the second mixing section 115, respectively. Air entering the mixing chamber 110 through the first air inlet 112 is also divided into two portions by the partition 300, with the two portions of air entering the first mixing section 114 and the second mixing section 115, respectively. The gas fuel and air in the first mixing section 114 are mixed separately, and the gas fuel and air in the second mixing section 115 are also mixed separately.

[0082] The first gas mixing section 114 is connected to the first ejection chamber 120. The mixed gas in the first gas mixing section 114 can enter the first cavity 141 through the first ejection chamber 120 and the guide chamber 130. The second gas mixing section 115 is connected to the second ejection chamber 150. The mixed gas in the second gas mixing section 115 can enter the second cavity 142 through the second ejection chamber 150. This prevents the mixed gas entering the first ejection chamber 120 and the mixed gas entering the second ejection chamber 150 from interfering with each other, thereby maintaining a stable flow rate of the mixed gas entering the first cavity 141 and the second cavity 142. Ultimately, this ensures that the flame burning above the first cavity 141 and the flame burning above the second cavity 142 remain stable.

[0083] The baffle 300 is removably disposed within the mixing chamber 110. Removing the baffle 300 from the mixing chamber 110 increases the space within the mixing chamber 110, facilitating the installation and removal of components within the mixing chamber 110. Specifically, a nozzle is disposed within the mixing chamber 110, connected to a gas fuel pipeline to allow gas fuel to enter the mixing chamber 110. Removing the baffle 300 provides the operator with more available space, facilitating the removal and installation of the nozzle from the mixing chamber 110. Of course, removing the baffle 300 also facilitates the installation and removal of other components within the mixing chamber 110.

[0084] To allow the partition 300 to be removably mounted within the gas mixing chamber 110, a first mounting groove 116 may be provided on the inner wall of the gas mixing chamber 110. The groove shape of the first mounting groove 116 matches that of the partition 300, allowing the partition 300 to be inserted into the first mounting groove 116, thereby securing the partition 300 within the gas mixing chamber 110. Specifically, when the partition 300 is positioned within the first mounting groove 116, the side of the partition 300 facing away from the first mounting groove 116 may abut against the inner wall of the gas mixing chamber 110, thereby maintaining stability of the partition 300.

[0085] The first mounting groove 116 has a first end and a second end that oppose each other. The first end has a notch, allowing the partition 300 to be inserted into the first mounting groove 116 through the notch. The second end is located at the bottom of the first mounting groove 116. The width of the portion of the first mounting groove 116 adjacent to the first end is greater than the width of the portion adjacent to the second end. This allows the first mounting groove 116 to have a structure that is wider at the top and narrower at the bottom. This facilitates the insertion of the partition 300 into the first mounting groove 116 and ensures that the partition 300 remains stable after being fully inserted into the first mounting groove 116.

[0086] Of course, the partition 300 may also be configured with one side being relatively thicker and the other side being relatively thinner. This allows the thinner side of the partition 300 to be engaged with the narrower side of the first mounting groove 116, while the thicker side of the partition 300 is engaged with the wider side of the first mounting groove 116. This allows the partition 300 to fit more tightly with the first mounting groove 116. This application does not impose any limitation on the specific shape of the partition 300.

[0087] The inner wall of the mixing chamber 110 can also be provided with a second mounting groove 117 opposite to the first mounting groove 116. The groove shape of the second mounting groove 117 also matches the outer shape of the partition 300, so that the other side of the partition 300 can be accommodated in the second mounting groove 117, thereby achieving the purpose of fixing both sides of the partition 300. In this way, after the partition 300 is installed in the mixing chamber 110, the stability and reliability of the partition 300 are better.

[0088] Of course, in other embodiments, the partition 300 may further include a first side panel 310 and a second side panel 320, wherein the first side panel 310 and the second side panel 320 are elastically connected, such that the spacing between the first side panel 310 and the second side panel 320 is variable. Specifically, in a natural state, there is a certain spacing between the first side panel 310 and the second side panel 320. Applying a force to the first side panel 310 and the second side panel 320 can reduce the spacing between the first side panel 310 and the second side panel 320, thereby reducing the overall thickness of the partition 300.

[0089] The width of the first mounting groove 116 is set to be smaller than the thickness of the partition 300 in its natural state. This allows the overall thickness of the partition 300 to be reduced by pressing the first side panel 310 and the second side panel 320. The partition 300 is then inserted into the first mounting groove 116 through the notch at the first end of the first mounting groove 116. When the partition 300 is completely located in the first mounting groove 116, the first side panel 310 and the second side panel 320 are released. The elastic force between the first side panel 310 and the second side panel 320 pushes them away from each other, causing the first side panel 310 and the second side panel 320 to respectively abut against the side walls of the first mounting groove 116. The friction between the first side panel 310 and the side walls of the first mounting groove 116, and the friction between the second side panel 320 and the side walls of the first mounting groove 116, ensures that the partition 300 remains stable in the first mounting groove 116, thereby preventing the partition 300 from separating from the first mounting groove 116.

[0090] To further ensure that the partition 300 is stable and secure within the first mounting groove 116, two opposing stoppers may be provided at the notch of the first mounting groove 116. The distance between the two stoppers is smaller than the width of the first mounting groove 116. Furthermore, when the first side panel 310 and the second side panel 320 are subjected to pressure, the thinnest thickness of the partition 300 is smaller than the distance between the two stoppers. This allows the partition 300 to be inserted into the first mounting groove 116. After the partition 300 is fully within the first mounting groove 116, the thickness of the partition 300 is greater than the distance between the two stoppers after the first side panel 310 and the second side panel 320 are released. Thus, the two stoppers act to block the partition 300, further preventing it from falling out of the first mounting groove 116.

[0091] To elastically connect the first side panel 310 and the second side panel 320, the partition panel 300 can be formed by folding a relatively tough plate in half. In this way, the first side panel 310 and the second side panel 320 are positioned opposite each other, connected on one side and separated on the other side. This allows the first side panel 310 and the second side panel 320 to be elastic. Specifically, the partition panel 300 can be made of stainless steel, formed by folding a stainless steel plate in half.

[0092] Of course, the first side panel 310 and the second side panel 320 can also be connected by an elastic member. Specifically, an elastic member can be set between the first side panel 310 and the second side panel 320. When an external force acts on the first side panel 310 and the second side panel 320 to bring the two closer to each other, the elastic member will be compressed. When the external force decreases or no longer acts on the first side panel 310 and the second side panel 320, the restoring deformation force of the elastic member can push the first side panel 310 and the second side panel 320 away from each other.

[0093] In some embodiments, a second air inlet 113 may be provided on the mixing chamber 110, so that the mixing chamber 110 has multiple air inlets to increase the air flow rate. Specifically, when the gas stove is required to produce a stronger flame, this can be achieved by increasing the flow rate of the gas fuel entering the mixing chamber 110. At the same time, the air flow rate requirement is also increased.

[0094] The second air inlet 113 can be set to an openable and closable structure. Specifically, when the flow rate of the gas fuel entering the mixing chamber 110 through the gas inlet 111 is small, the second air inlet 113 can be set to a closed state. At this time, the external air can only enter the mixing chamber 110 through the first air inlet 112. In this way, the amount of air entering the mixing chamber 110 can be coordinated with the amount of gas fuel entering the mixing chamber 110 through the gas inlet 111, so that the concentration of each component of the mixed gas reaches the most suitable concentration.

[0095] When the flow of gas fuel entering the mixing chamber 110 through the gas inlet 111 increases, the second air inlet 113 can be opened to increase the flow of air entering the mixing chamber 110, so that the amount of air in the mixing chamber 110 matches the amount of gas fuel.

[0096] Specifically, a removable sealing plate 400 is provided on the burner body 100. When the sealing plate 400 is connected to the burner body 100, the sealing plate 400 blocks the second air inlet 113, so that the second air inlet 113 is closed. When the sealing plate 400 is removed from the second air inlet 113, the second air inlet 113 is in an open state. The burner body 100 can be provided with screw holes set along the edge of the second air inlet 113, and the sealing plate 400 can be provided with screw holes corresponding to the screw holes on the burner body 100. By aligning the above two screw holes and screwing in the bolts, the sealing plate 400 can be fixed to the burner body 100 to block the second air inlet 113. The sealing plate 400 and the burner body 100 can be tightly connected by bolt connection. Of course, the sealing plate 400 and the burner body 100 can also be connected in a snap-fit ​​manner, which can facilitate the removal of the sealing plate 400. This application does not limit the specific connection method between the sealing plate 400 and the furnace head body 100.

[0097] Example 2

[0098] Based on the above-mentioned gas burner, the present application also proposes a gas stove including the above-mentioned gas burner.

[0099] The aforementioned gas stove also includes a gas distribution plate 500, which is disposed on the burner body 100 and opposite the gas supply cavity 140. Specifically, the gas distribution plate 500 is disposed above the gas supply cavity 140 and functions to introduce secondary air, allowing external air to enter the gas supply cavity 140 through the gas distribution plate 500, thereby ensuring more complete combustion of the mixed gas within the gas supply cavity 140. A first connecting member 160 may be disposed on the burner body 100, and a second connecting member 510 may be disposed on the gas distribution plate 500. The first connecting member 160 and the second connecting member 510 cooperate to secure the gas distribution plate 500 to the burner body 100 and limit radial displacement of the gas distribution plate 500.

[0100] Specifically, the first connecting member 160 can be a step opened on the burner body 100, and the second connecting member 510 can be a step opened on the gas distribution plate 500. The steps on the burner body 100 and the steps on the gas distribution plate 500 cooperate with each other, so that the gas distribution plate 500 can be snapped onto the burner body 100, thereby limiting the radial displacement of the gas distribution plate 500 to keep the gas distribution plate 500 stable.

[0101] Of course, it should be noted that the gas burner disclosed in this embodiment can also be applied to other gas stoves, such as gas stoves that use liquid fuel as raw material.
